IMPROVEMENT IN VALVES FOR WATER-PIPES.

Specification forming part of Letters Patent No. 144,356, datedVNovember 4, 1873; application filed August 27, 1873.

To all 'whom it may concern:

i Be it known that I, D. GOEFE Pnrrrs, of New Haven, in the county ofNew Haven and State of Connecticut, have invented a new Improvement inValve for Water-l ipes5 and I do herebyT declare the following, whentaken in connection with the accompanying drawings and the letters ofreference marked thereon, to be a full, clear, and ekactdescrip` tion ofthe same, and which said drawings constitute part of this speciiieation,and represent, in-

Figure l, aside view, and in Fig. 2 a longitudinal central sectionenlarged.

This invention relates to an improvement in valves for introduction tocementdined water-pipes. In valves for this purpose it is desirable thatthe coupling between the pipe and valve should be made the same as forthe sections of pipe-that is, so that a sleeve may be slipped over thejoint between the valve and pipe, and there cemented in the usualmanner; but, as the section which must be attached to the valve for thispurpose must be cast with the valve, it exposes a large amount ot'surface of the iron to the action of the water, which rapidly corrodesor oXidizes. The object of my invention is to overcome this difficulty;and it consists in constructing' the valve with a neck projecting fromeach side, the external diameter corresponding to the pipe with whichthe valve is to be connectedthat is to say, so that a sleeve may passover and cover the joint between the pipe and the neck of the valve-andcoating the neck from the valve-seat outward with cement.

A is the case, within which the valve B is arranged, and from each sidea tubular projection or neck, G, is formed, corresponding to thediameter of the pipe to be connected. D D are valve-seats, which aremade from brass or other metal which will not oxidize to any extent bycontact with water. These are set into the valve-chamber, as shown in1Eig. 2, and between which the valve B works.

The valve may be operated in any known manner.

The internal diameter of the neck C is less than that of the valve-seatD, so that the sea-t I) forms a shoulder in the neck. Frein the seats Dthe projections Care internally coated with a cement lining, E, asdenoted in solid black, Fig. 2, the internal diameter corresponding tothe diameter of the pipe to be cou nected.

In making connections, the end of a section of pipe is butted againstthe end of one of the projections, and the joint covered and secured inthe usual manner of connecting cement pipe.

Thus I protect the water-way in the valve, so that the water flowingthrough does not come in contact with the metal; and I am enabled tocouple the pipe to the valve in the Same manner as sections of pipe arecoupled; and I avoid the. difficulties ot the common valve.

In some valves, and particularly in large valves, I coat thevalve-chamber between the valve-seats with cement, as denoted in solidblack below the valve in Fig. 2.

Y I claim as my invention- The herein-described valve for water-pipes,consisting of the valve-chamber proper and the valve workin g therein,the said chamber formed with projections or necks C concentric with thevalve-seats, and the interior ot' the necks, from the valve-seatsoutward, lined with cement, substantially as described.
